you could maybe do something like
function intervalsToType(input) { // input = '1P 3M 5P'
var input_array = input.split(' '); // ['1P', '3M', '5P']
var chordInC_array = input_array.map(int => tonal.transpose('C4', int)); // ['C4', 'E4', 'G4']
var chordInC_string = chordInC_array.join(' '); // 'C4 E4 G4'
var chord = tonal.chord.parse(chordInC_string); // {tonic: 'C', type: 'M'}
return chord.type // 'M'
}
I haven't tested that but something along those lines might work

Thanks for the reply @mrjacobbloom
Just a note: tonal can work with arrays or strings, there's no need of conversion. So your code can be simplified to:
const input = '1P 3M 5P'
tonal.chord.detect(tonal.harmonize(input, 'C')) // => ['CM', 'Em#5']
Edited:
or, more similar to your code:
const notes = tonal.harmonize(input, 'C');
const chord = tonal.chord.parse(notes);
return chord.type;

Solution for tonal 1.0.0:
const intervals = ["1P", "3M", "5P"];
const chroma = Tonal.PcSet.chroma(intervals);
Tonal.chord.names(chroma); // => ["M", "Maj"]
